After declarations from the World Health Organization and the U.S. government that monkeypox is a public health emergency, attention is turning to the pharma industry’s response to the disease. Vaccines look likely to play a crucial role in controlling monkeypox – but could antivirals play a significant part as they did in the COVID-19 pandemic?
A move by Chimerix Inc. to strengthen its balance sheet by $225 million through the sale of smallpox drug Tembexa (brincidofovir) to biodefense specialist Emergent Biosolutions Inc. and extend its cash runway into 2026, should have proved a big win. Instead, shares (NASDAQ:CMRX) plunged nearly 61% May 16 on worry that Chimerix might be handing off a likely profitable program to fund a riskier oncology pipeline, a concern heightened by recent U.S. FDA feedback indicating lead oncology program ONC-201 might not be eligible for accelerated approval as previously expected.
Chimerix Inc., which already has COVID-19 and smallpox therapeutics in clinical trials, has acquired privately held Oncoceutics Inc., bringing ONC-201, a small-molecule dopamine receptor D2 antagonist and caseinolytic protease agonist for treating recurrent gliomas harboring the H3 K27M mutation, into the fold.
A pair of good-news items from Chimerix Inc. pushed the Durham, N.C.-based company’s stock (NASDAQ:CMRX) to $2.15, closing up 64 cents, or 42%, higher as backers reacted to near-term NDA plans for smallpox countermeasure brincidofovir (BCV) and the start of a phase II/III trial with dociparstat sodium (DSTAT) in COVID-19 patients with acute lung injury (ALI).
